First of all, I'd like to thank everyone who has spent all this time and effort into making plugins for the community to use. I'm in awe of those of you who are able to do it!

My idea was a Treasure Cache tracker, very similar to Mathwold's Roving Threat tracker, RTPlugin, which is very handy! It really could be expanded to include things like the Rare Mordor Chests and Lore Pages in Mordor, but I'd be happy with just the Treasure Caches around Middle-earth.

As Robhupf said, MoorMap already shows Treasure Cache locations prior to Mordor. The next release will also have Rare Treasure chests as well as the Mordor pages. I finally got time to start capturing the annotations so it should be out in a week or two. FWIW, TerrainMap also shows these default annotations (their data files come from the same database).
